Apparatus And Method For Improved Signal Fade Out In Different Domains During Error Concealment
Abstract: An apparatus for decoding an audio signal is provided. The apparatus comprises a receiving interface (110) wherein the receiving interface (110) is configured to receive a first frame comprising a first audio signal portion of the audio signal and wherein the receiving interface (110) is configured to receive a second frame comprising a second audio signal portion of the audio signal. Moreover the apparatus comprises a noise level tracing unit (130) wherein the noise level tracing unit (130) is configured to determine noise level information depending on at least one of the first audio signal portion and the second audio signal portion wherein the noise level information is represented in a tracing domain. Furthermore the apparatus comprises a first reconstruction unit (140) for reconstructing in a first reconstruction domain a third audio signal portion of the audio signal depending on the noise level information if a third frame of the plurality of frames is not received by the receiving interface (110) or if said third frame is received by the receiving interface (110) but is corrupted wherein the first reconstruction domain is different from or equal to the tracing domain. Moreover the apparatus comprises a transform unit (121) for transforming the noise level information from the tracing domain to a second reconstruction domain if a fourth frame of the plurality of frames is not received by the receiving interface (110) or if said fourth frame is received by the receiving interface (110) but is corrupted wherein the second reconstruction domain is different from the tracing domain and wherein the second reconstruction domain is different from the first reconstruction domain. Moreover the apparatus comprises a second reconstruction unit (141) for reconstructing in the second reconstruction domain a fourth audio signal portion of the audio signal depending on the noise level information being represented in the second reconstruction domain if said fourth frame of the plurality of frames is not received by the receiving interface (110) or if said fourth frame is received by the receiving interface (110) but is corrupted.
